In summary, the conversation is about performing a reaction between sodium thiosulphate and hydrogen peroxide in a laboratory setting. The individual is asking for advice on how to carry out the reaction and if there are any potential harmful effects or precautions to take. They mention having a titration setup and ask if there are any potential problems with performing the experiment under normal conditions. The expert suggests consulting literature and MSDS for more information.

Hii..

I am planning to perform a reaction between "Sodium Thio sulphate and Hydrogen peroxide"

Na2S2O3+2 H2O2---->1/2 Na2S3O6 + 1/2 Na2SO4 + 2 H20

CAN ANY ONE TEL ME HOW THIS REACTION ...can be carried in the laboratory
...
Is there any harmful effects with this reaction..?

if so please let me know...ur views...


Thank u
Shri..

You would probably need a titration setup.

There should not be anything major, however you should still consult with literature and MSDS for the experiment.
 

FAQ: Reaction Feasibility: Na2S2O3+2 H2O2

What is the reaction between Na2S2O3 and H2O2?

The reaction between Na2S2O3 (sodium thiosulfate) and H2O2 (hydrogen peroxide) is a redox reaction, where the thiosulfate ion is oxidized to form sulfate ions and the hydrogen peroxide is reduced to form water. This reaction is commonly used in chemical demonstrations, such as the "Elephant Toothpaste" experiment.

Is the reaction between Na2S2O3 and H2O2 spontaneous?

The spontaneity of a reaction depends on the change in Gibbs free energy (ΔG). In this case, the reaction is not spontaneous under standard conditions (ΔG > 0), but can be driven forward by increasing the temperature or concentration of reactants.

What are the products of the reaction between Na2S2O3 and H2O2?

The products of this reaction are sodium sulfate (Na2SO4) and water (H2O).

Can this reaction be reversed?

No, this reaction is not reversible. The products, sodium sulfate and water, cannot spontaneously react to reform sodium thiosulfate and hydrogen peroxide.

How does the concentration of reactants affect the rate of this reaction?

The rate of this reaction is directly proportional to the concentration of both reactants. Increasing the concentration of Na2S2O3 or H2O2 will result in a faster rate of reaction. However, increasing the concentration of only one of the reactants will not significantly affect the rate, as the reaction is limited by the presence of both reactants.
